Appli-cation flied September 11, 1905. Serial No. 277 ,959.

To all 'whom 'it may' concern:

Be it known that I, FRANCIS G. CRoNE, a

` citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Tire Protector, of `which the following is a specification.

My invention relates to pneumatic tire protectors or Creepers.

My chief objects have beento provide means, readily attachable to any pneumatic l tire wheel, which can be used in case the tire 1s punctured or defective to protect it from being rim cut g also to provide means for preventing the tire from creeping on slippery or .icy roads.

1 is a pressed oval stri of metal having a` roll 2 and provided wit a lug. 3 through which a bolt 4 may pass to secure it to a corresponding, adjo' section. The depending flange 5 projects elow the face of the rim 6 of the wheel 7 so that at any suitable point or oints 8, bolt holes 9 may .be provided.

`he bolt holes are so place hat when the tire protectorlis in itsv roper position the two adjoining holes will e on o posite sides of a spoke 10 and bolts passing tlhrou h such holes will engage with a strap 11 an when screwed in position firmly hold the protector in place against' the rim 6 and tire 1,2 of the wheel 7.

For the purpose of more rigidly holding 'the protector 1 in place, I provide set screws 13 which may be forced against the rim 6 and hpld the said rim and protector irmly in p ace. y

It is apparent from the foregoing descrip tion of my invention that the sections of my protector can readily be attached to 'an wheel and that when so attached they bearthe weight of the load exerted on the wheel whenever the pneumatic tire is de# Hated to any predetermined degree..v Manifestly my protector may be so regulated that it will at all times bear all the weight of the superimposed load or it may bear only a part of 1t which it may share with the tire whether the tire be pneumatic or solid. Thus my invention may be kept attached to the wheel at all times and not be used or it may readily be attached and detached as desired. i

It will be evident that when a' wheel rovided with my improvement tends to s 'd, as the tread point of the tire is rolled slightly to one side by the lateralpressure due to the skidding movement of the vehicle, the tire is attened at the tread oint to a suHicient extent to permit the perlphery of the protector to en age against the pavement or roadway and tins check the tendency to skid.

'By means of myinvention therefore I am able to prevent pneumatic tires-from being rim cut and thus I greatly lengthen the life of the tire in addition to being able by means of a very simple and readily attachable and detachable device, to prevent the wheels from skidding or creeping.

From the foregoing it will be evident that the7 rotectors may be moved back and forth spokes of the wheel and thus within certain `mits be placed in any predetermined relation with the tire of the Wheel.

Having thus described my invention, what I claim is:

1. The combination with a vehicle wheel and a tire attached thereto of a tire rotector comprisin 4a plurality of circular p ates provided eripheral tread surfaces and means for rigldly securin said plates to said wheel so that the perip ery of said plates may bear any predetermined relation to the penphery of said tire.

2. The combination with a vehicle wheel and a tire attached thereto of a tire protector comprisin segmental circular plates, the segments aving similar outwar ly and inwardly curved rims to form a tread, and depending flanges and means for securing sind flanges tothe spokes of the wheel.

\ 3. The combination with a vehicle Wheel and a tire attached thereto of a plurality of segmental, circular tire protectors, the segments havin similar outwardly and inwardly curve rims to form a tread, dependin flanges and straps and bolts for sec-umn said anges at `their ends with each other an with the spokes of the wheel, lugs on the ends of said segments and bolts uniting said lugs to rigidly secure said segments to each other.

4. The combination with a vehicle Wheel a rim and a tire attached thereto of a tire prof3 tector comprising an outside rim, a dependl ing flange, means forrigid'ly securing said protector to the spokes of said Wheel and setscrews threaded through said protector and i bearing against the tire rim to further secure' the protector to the Whee1.-

In testimony whereof, I have hereunto set my hand in the .presence of two Witnesses.
